RADIAL DRIVING \VHEEL FOR LOCOMOTIVES.

Application filed June 30, 192 1.

To all whom it may concern:

Be it known that we, JAo UEs L. VAUGLAIN and JOHN A. PFEIFFER, citizens of the United States, residing, respectively, in

Havertord, Montgomery County, Pennsylvania, and Philadelphia, Pennsylvania, have invented certain Improvements in Radial Driving l/Vheels for Locomotives, of which the following is a specification.

This invention relates to certain improve ments in radial driving wheels for locomotives, such as described in the patent granted to Kenneth Rushton on the twelfth day of October, 1920, No. 1,355,699.

The object of the present invention is to improve the construction of a radial driving axle, and to reduce the number of parts, thereby making the device more substantial than heretofore.

In the accompanying drawings:

Fig. 1 is a longitudinal sectional view of a radial driving axle illustrating our invention, the section being on the line 11, Fig. 2;

Fig. 2 is a transverse sectional view on the line 22, Fig. 1;

Fig. 3 is a detached perspective view of the hub;

Fig. 1 is a detached perspective view of one of the driving heads that engages the hub;

Fig. 5 is a sectional view of one of the parts of the wheel structure;

Fig. 6 is a detached perspective view of one of the swivel blocks; and

Fig. 7 is a detached perspective view of one of the pins on which the swivel blocks are mounted.

Referring to the drawings, 1 is an axle on which are the driving cranks. These axles are mounted in suitable boxes on the frame of the locomotive, as in the patent hereinbefore referred to. Loosely mounted on the axle is a hub 2, having a bushing 8. Secured to the axle by keys 1 are two driving heads 5, which have projecting jaws 6 that are spaced apart, as shown in Fig. 4.

On the hub 2 are aws 7, which are shaped so as to enter the space between the jaws 6 in the driving heads. The ends of the jaws of one part do not come in contact with the base of the openings in the other part. This spacing of the two parts allows a certain Serial No. 723,186.

In the hub are sockets 8., in which are located the blocks 9, which are shaped as shown in Fig. 6. These blocks are mounted on pins 10, which are located in the wheel structure 11, as clearly shown in Figs. 1 and 2.

The wheel structure 11 consists of two parts 12, having flanges 18, which are secured together by bolts 14. At the opposite ends of the parts 12 of the wheel structure are wheel centers 15, on which are the tires 16 of the wheels 1.7. The inner portion of each section 12 is shaped to form a socket 18, in which the hub 2 is located. The periphery of the hub conforms to the socket so that the wheel structure is free to turn on the center a: and accommodate itself to the curves of the track.

The wheel structure 11 is driven from the axle through the driving heads 5, hub 2, pivot blocks 9, and the pins 10. On each end or" the hub 2 is a flange 19. Between this flange and a ring 20, secured to the wheel structure within each wheel, is a coil spring 21. These springs tend to hold the wheel structure in a central position, but either spring will yield when the locomotive is passing around a curve. When the locomotive resumes its straight course, the springs return the structure to a central po sition.

We claim:

1. The combination of a radially driven axle; a hub loosely mounted thereon and having jaws at each end; and driving heads secured to the axle on each side of the hub, said heads having jaws extending into the spaces between the jaws of the hub and driven thereby.

2. The combination of an axle; a centrally located hub loosely mounted thereon and having jaws at each side, said jaws being spaced apart; a driving head secured to the axle on each side of the hub and having aws extending into the spaces between the jaws of the hub; a wheel structure mounted on the hub and having a socket, the periphery of the hub being shaped to fit the socket; and means for coupling the hub to the socket.

3. The combination of an axle; a centrally located hub mounted loosely thereon and having jaws at each end; a driving head secured t0 the axleon each side of the hub and having jaws extending into the spaces between the jaws of the hub; a wheel structure shaped to form a socket, the periphery of the hub being a segment of a ball, and being located in the socket of the wheel structure said hub having sockets; blocks mounted within the sockets; and pins, on the wheel structure, on which the blocks are swiveled.

4. The combination of an axle; a hub loosely mounted thereon, the periphery of the hub being in the form of a segment of a ball, said hub having a series of jaws at each end spaced apart; a driving head secured to the axle on each side of the hub and having jaws extending into the spaces between the jaws of the hub; a wheel structure enclosing the hub and the driving head and having wheels thereon, the central portion of the structure being in the form of a socket, in which the hub is mounted; a flange at each end of the hub; rings secured to the wheel structure within the wheel; and a coiled spring located between the flange of the hub and the ring, and tending to retain the wheel structure in a central position on the axle.
